I can't stress this enough. An option when challenging that prevents a non driver and above from joining your battle when selected is an incredibly necessary feature, especially with the first official tournament in BW2 starting tomorrow. A ton of matches will be done on PS! and the privacy of the battlers is necessary when desired. Due to Grand Slam, it might be prudent to put completing this feature near the top of the to-do list.
